我市棚式栽培食用菌比较普遍,本文主要介绍棚式栽培金针菇易出现的问题及解决办法。 1 菌丝迟迟长不满不能解袋出菇 1.1 主要原因 ①菌种用量少。②菌丝长到2/3时,因袋内氧气不足,影响了菌丝的长速。③发菌期培养温度不适或袋料过干、过湿或污染严重,影响了菌丝的正常生长,延长了菌丝生长期。 1.2 处理办法 ①接种量7％～8％增加到10％～12％。②菌丝长到1/3时,把扎口解开,增加向袋供氧气,加速菌丝生长。③发菌期保持菌袋温度19～20℃,保证含水量70％,争取30～35天让菌丝长满袋。④把杂菌污染处理在最佳的状态,一是在拌料时每100kg培养料加入50％的多菌灵0.01％,生石灰2％～3％,石膏1％,充分搅拌均匀;二是进行熟料栽培,把料袋装锅在100℃下灭菌8～10小时;三是把全部接种用具放入接 Shed cultivated edible fungi in our city is more common, this article describes the shed cultivation of Flammulina velutipes prone problems and solutions. 1 mycelium delay long dissatisfaction can not solution bags fruiting 1.1 The main reason ① strain with less. ② mycelium grows 2/3, due to lack of oxygen in the bag, affecting the mycelium’s long-speed. ③ germination temperature training ill or bag over dry, too wet or heavily polluted, affecting the normal growth of mycelium, extending the mycelial growth period. 1.2 approach ① vaccination 7% to 8% increased to 10% to 12%. ② mycelium grows to 1/3, the Zhakou unlock, increase oxygen supply to the bag, accelerate mycelium growth. ③ germination period to maintain bag temperature 19 ~ 20 ℃, 70% moisture content, for 30 to 35 days let mycelium covered with bags. ④ bacteria in the best treatment of pollution, first, when the feed material per 100kg of culture medium when adding 50% carbendazim 0.01%, 2% ~ 3% quicklime, gypsum 1%, stir well; second is to carry out Clinker cultivation, the material bagged pot sterilization at 100 ℃ for 8 to 10 hours; Third, put all the vaccination appliances into the
